MOTOR VEHICLE.

'Specificationof Letters Patent. Patgnted A L 1922 Application filedQctober 12, 1916. Serial No. 125,222.

To all whom'z't may concern:

Be it known that I, JEssE G. VINoriN'r, a

citizen of the United States, and resident of. Detroit, Wayne County,State of Mich1 an,

have invented certain new and useful mprovements-in Motor Vehicles, ofwhlch the following is a specification.

This invention relates to niotor vehicles and particularly to the clutchmechanism vide a clutch brake that may have its various parts assembledand the brake? as a whole readily applied to and removed from the clutchcasing;

Another object of'the invention is to. pro vide a clutch'br'ake that'isbodily adjustable relatively to and longitudinally of the axis of theolutch.

Other objects of the inventibn will appear from the followingdescription taken in connection with the drawings-which form a part ofthis specification, and in which,

Fig. 1 is a verticallongitudinal section through a clutch and associatedparts of a motor vehicle embed ing the mventlong Fig. 2 is a verticatransverse sectlon approximately on the line 2-2 of Fig. 1;

Fig. 3 is a detail planview of the'clutch casing cover; and

Fig. 4:. is an enlarged detail view. Referring to the drawings, 10represents a motor vehicle crank shaft and 11 is a fiywheel securedthereto. These parts constitute the driving element of a clutch 12.

13 is a shaft axially aligned with the shaft 10 and constitutes thedriven element of the clutch. A casing 1 1 surrounds all of these parts,housing and supporting them. The

shaft has a bearing 15 in the casingand the shaft 13 has a bearing 16therein and a bearing 17 for its front end in the end of the shaft 10.

The clutch 12 comprises an outer drum 18 an inner durm 19, interengagingdisks 20, a .clutch spring) 21, a sleeve 23, and a shifter collar 22 ywhich the clutch is operated. The clutch is of the usual dry plate ordisk form and its construction and operation will be ieadily understood,it is believed, from the drawings and the'above description. It is shownin engaged position in Fig. 1, and the shifter collar 22 is adapted tomove the sleeve 23 to the right on the shaft 13 to compress the spring21 to disengage the plates 20 from clutchin contact. In other words thespring 21 yiel ingly retalns the clutch in engaged position. When aclutch of the above type is used in motor vehicles in connection withsliding gear changing mechanism, it is found desirable to aquickly stopthe shaft 13 from spinnlng as soon as the clutch is'released. This isfor the purpose of facilitating the gear change, and in the presentinvention a simple and effective form of clutch brake is used to retardthe rotation or stop the spinning of said shaft 13. The form of theinvention shown in the drawing will now be described. 1 i 1 Upon thesleeve 23 is formed or secured a disk 24 which is shown as of slightlyconical shape. Immediately above this disk the casingl l is formed withan opening 25 which gives easy access to the various parts of theclutch. This opening is closed by a detachable cover 26 and upon theinside of the cover is mounted a clutch brake 27. This brake is in theform ofa lever pivoted at 28 and having ashoe part 29 which is adaptedto co-operate with the disk 24 herein above described, and a part 30which is in the form of a shank and extends through the cover 26 to theoutside thereof. Surrounding the shank 3O isa spring 31 adjustable as bynut 32. The pivot 28 is on a bracket 33 which has a squared portion 34adapted to set in a pressed up part 35 of the cover 26, and it is alsoformed with a bolt part 36 which extends through a slotx37 in thispressed up part of said cover. A plate 38 is adapted to cover the slot37 and the bolt 36 also extends through this plate, a nut 39 securingthebracket. 33 to the plate and cover. It will be undersood that byloosening the nut .39 the bracket 33 may he moved in the slot '29 of theclutch brake, and any further movement of the collar will cause theclutch brake to move on its pivot 28 and compress the spring 31 therebyincreasing the friction of the disk 24 against the shoe 29 andconsequently retarding'the rotation of the collar 23 and consequentlythe shaft 13 to a greater degree. When the clutch is re-e'ngaged the,

reverse operation of the clutch brake takes place and when the clutch isfully engaged there is, of course, no contact and consequently no dragbetween the disk 24 and the clutch brake.

It will be understood furtherthat the entire clutch brake may beassembled on the cover 26tan'd the cover and the assembled brake maythen be applied to the openin in the casing 14 after the clutch is in pace therein. The clutch-brake may then be bod- .ily moved longitudinallyof the clutch for constructions may 'be made without departing from thesplritor-scope ofthe invention as defined the claims.

Having thus described my invention, what I claim and desire to secure byLetters Pat- I the casing. an

'1. The combination with a clutch and a controlled brake pivotallymounted on the inside of said casing and having a shoe adapted tocontact with said disk. i

3; The combination with a clutch and the casing therefor, of a diskmounted on the movable member of the clutch, said casing having anopening above said disk, a cover for said opening, and a clutch brakemount- 'casing therefor, of a,disk'mounted on the ed on said cover.

4. The combination with a clutch and the movable member ofytheclutch,-said casing 1 having an opening above said disk, a cover forsaid opening ,a clutch brake mounted on said cover, and means for bodilyadjusting said clutch brake relatively 'to the clutch. 5. Thecombination with a clutch, and a casing enclosing said clutch, of apivotally supported-clutch brake carried by said casing, and means foradjust ng support of said brake longltu 1 clutch axis.

'6. The combination with a clutch and a the pivotal nally of the casingtherefor, of a clutch brake 'compris- U ing a lever pivoted inthe casingandvhaving a part adapted to act on said clutch as a brake and anotherpart extending through the casing, 'a spring on the part extendingthrough the casing, and means for bodily shifting said clutch brakerelatively to the clutch. I v

7, The combination with a clutch and a casing therefor, of a clutchbrake compris-v ing a lever pivoted in the casing and having a shoeadapted to act on said clutch to stop spinning thereof and having ashank extending through the casing to the outsidethereof, an adjustablespring on said shank, and means for bodily shifting the clutch brakelongitudinally of the clutch axis.

8. The combinatlon with a clutch and a casing around the clutch, saidcasing having an opening in its wall, a removable cover for saidopening, and a clutch brake mounted upon and removable with said coverand adapted to retard the rotation of one of the clutch members when theclutch is disengaged. I y

9. The combination with a clutch and a casing therefor, said casinghaving an opening in its wall, a cover removably secured over saidopening, a brake supporting means adjustably mounted on said cover andremovable therewith, and a brake mounted on said means and cooperatingwith one of the clutch members.

-10. In a motor vehicle, in combination, a clutch casing having aremovable cover, a clutch withinthe casing, and a brake carried bysaidcover arranged to retard the rotation of, the driven member of theclutch when the clutch is disengaged.

11. In combination with a clutch casing having a removable cover, aclutch within the casing, means for retarding the rotation of the drivenclutch member when the clutch, is disengaged including a supportremovably fastened to said cover and a brake member mounted on saidsupport.

12. In combination with a clutch casing having aremovable cover, aclutch't herein, a

brake member arranged to retard the rotation of the driven clutchmember, when the clutch 'is disengaged, said brake member being mountedon said cover for adjustment axially of the clutch.

13. In combination with a clutch casing having a removable cover, aclutch therein, a support secured 'to' the cover by a bolt and slotconnection, the slot being parallel with the axis of the clutch and abrake member carried by said support arranged to retard the rotation ofthe driven clutch member when the clutch is disengaged;
